I am new to PHP and just tested out using NuSoap to query Google database. The code is written by Harish Kamath. However, it doesn't work without error message. The web server I used support PHP. Also I downloaded the required nusoap.php class file and put it in the same directory with nusearch.php, which query Goodgle database and I have Google's licence key for its APIs. The code is as following:
<html> <head><basefont face="Arial"></head> <body> <?
if (!$_POST['q'])
{
?>
<h2>Search</h2>
<form action="<?=$_SERVER['PHP_SELF']?>" method="post">
Search term: <input type="text" name="q">
</form>
<?
}
else
{
// include the class
include("nusoap.php");// create a instance of the SOAP client object
$soapclient = new soapclient("http://api.google.com/search/beta2";);// uncomment the next line to see debug messages // $soapclient->debug_flag = 1;
print("Before params"); // testing
// set up an array containing input parameters to be
// passed to the remote procedure
$params = array(
'key' => 'LHZMFvNQFHJ/jGT0d6N8Iu83QVsz49rr', // Google license key
'q' => $_POST['q'], // search term
'start' => 0, // start from result n
'maxResults' => 10, // show a total of n results
'filter' => true, // remove similar results
'restrict' => '', // restrict by topic
'safeSearch' => true, // remove adult links
'lr' => '', // restrict by language
'ie' => '', // input encoding
'oe' => '' // output encoding
);print("before invoke the doGoogleSearch method");
// invoke the method on the server
$result = $soapclient->call("doGoogleSearch", $params,"urn:GoogleSearch", "urn:GoogleSearch");
print("before printing results");
// print the results of the search
if ($result['faultstring'])
{
?>
<h2>Error</h2>
<? echo $result['faultstring'];?>
<?
}
else
{
?>
<h2>Search Results</h2>
Your search for <b><?=$result['searchQuery']?></b> produced <?=$result['estimatedTotalResultsCount']?> hits.
<br>
<ul>
<?
print("before displaying result");
if (is_array($result['resultElements']))
{
foreach ($result['resultElements'] as $r)
{
echo "<li><a href=" . $r['URL'] . ">" . $r['title'] . "</a>";
echo "<br>";
echo $r['snippet'] . "(" . $r['cachedSize'] . ")";
echo "<p>";
}
}
?>
</ul>
<?
}
}
?>
</body>
</html>Would be very much appreciated if someone can help me out. Thanks,
Daniel
